Get real position in lexer. Added example - netbeans

I writing editor with netbeans7 and ANTLR4
I have line in my.g4 file
Label : {(getCharPositionInLine()==0)}? ID;
That works well for static files, but while editing getCharPositionInLine() returns 0 often in other places.
How get a real position in lexer?
updated
I created example with this problem
https://github.com/daimor/SimpleANTLR

Your error is likely in the way you are constructing your lexer and/or input stream (i.e. code that you have not shown here). The predicate you describe above will work as expected for an ANTLR 4 lexer.
Also, if getCharPositionInLine()==0, then exactly one of the following conditions is also true:
_input.index()==0
_input.LA(-1)=='\n'

Cimplicity Screen - one object/button that is dependent on hundreds of points

So I have created a huge screen that essentially just shows the robot status for every robot in this factory (individually)… At the very end of the project, they decided they want one object on the screen that blinks if any of the 300 robots fault. I am trying to think of a way to make this work. Maybe a global script of some kind? Problem is, I do not do much scripting in Cimplicity, so any help is appreciated.
All the points that are currently used on this screen (to indicate a fault) have very similar names… as in, the beginning is the same… so I was thinking of a script that could maybe recognize if a bit is high based on PART of it's string name characteristic. The end will change a little each time, but I am sure there is a way to only look for part of a string and negate the rest. If the end has to be hard coded, that's fine.
You can use a Python script in Cimplicity.
I will not go into detail on the use of python in Cimplicity, which is well described in the documentation indicated above.
Here's an example of what can be done... note that I don't have a way to test it and, of course, this will work if the name of your robots in the declaration follows the format Robot_1, Robot_2, Robot_3 ... Robot_10 ... Robot_300 and it also depends on the Name and the Type of the fault variable... as you didn't define it, I imagine it can be an integer, with ZERO indicating no error. But if you use something other than that, you can easily change it.
import cimplicity
(...)
OneRobotWithFault = False
# Here you get the values and check for fault
for i in range(0, 300):
pointName = f'MyFactory.Robot_{i}.FaultCode'
robotFaultCode = cimplicity.point_get(pointName)
if robotFaultCode > 0:
OneRobotWithFault = True
break
# Set the status to the variable "WeHaveRobotWithFault"
cimplicity.point_set("WeHaveRobotWithFault", OneRobotWithFault)

How to encode normalized(A,B) properly?

I am using clingo to solve a homework problem and stumbled upon something I can't explain:
normalized(0,0).
normalized(A,1) :-
A != 0.
normalized(10).
In my opinion, normalized should be 0 when the first parameter is 0 or 1 in every other case.
Running clingo on that, however, produces the following:
test.pl:2:1-3:12: error: unsafe variables in:
normalized(A,1):-[#inc_base];A!=0.
test.pl:2:12-13: note: 'A' is unsafe
Why is A unsafe here?
According to Programming with CLINGO
Some error messages say that the program
has “unsafe variables.” Such a message usually indicates that the head of one of
the rules includes a variable that does not occur in its body; stable models of such
programs may be infinite.
But in this example A is present in the body.
Will clingo produce an infinite set consisting of answers for all numbers here?
I tried adding number(_) around the first parameter and pattern matching on it to avoid this situation but with the same result:
normalized(number(0),0).
normalized(A,1) :-
A=number(B),
B != 0.
normalized(number(10)).
How would I write normalized properly?
With "variables occuring in the body" actually means in a positive literal in the body. I can recommend the official guide: https://github.com/potassco/guide/releases/
The second thing, ASP is not prolog. Your rules get grounded, i.e. each first order variable is replaced with its domain. In your case A has no domain.
What would be the expected outcome of your program ?
normalized(12351,1).
normalized(my_mom,1).
would all be valid replacements for A so you create an infinite program. This is why 'A' has to be bounded by a domain. For example:
dom(a). dom(b). dom(c). dom(100).
normalized(0,0).
normalized(A,1) :- dom(A).
would produce
normalize(0,0).
normalize(a,1).
normalize(b,1).
normalize(c,1).
normalize(100,1).
Also note that there is no such thing as number/1. ASP is a typefree language.
Also,
normalized(10).
is a different predicate with only one parameter, I do not know how this will fit in your program.
Maybe your are looking for something like this:
dom(1..100).
normalize(0,0).
normalize(X,1) :- dom(X).
foo(43).
bar(Y) :- normalize(X,Y), foo(X).

Mozilla Deep Speech SST suddenly can't spell

I am using deep speech for speech to text. Up to 0.8.1, when I ran transcriptions like:
byte_encoding = subprocess.check_output(
"deepspeech --model deepspeech-0.8.1-models.pbmm --scorer deepspeech-0.8.1-models.scorer --audio audio/2830-3980-0043.wav", shell=True)
transcription = byte_encoding.decode("utf-8").rstrip("\n")
I would get back results that were pretty good. But since 0.8.2, where the scorer argument was removed, my results are just rife with misspellings that make me think I am now getting a character level model where I used to get a word-level model. The errors are in a direction that looks like the model isn't correctly specified somehow.
Now I when I call:
byte_encoding = subprocess.check_output(
['deepspeech', '--model', 'deepspeech-0.8.2-models.pbmm', '--audio', myfile])
transcription = byte_encoding.decode("utf-8").rstrip("\n")
I now see errors like
endless -> "endules"
service -> "servic"
legacy -> "legaci"
earning -> "erting"
before -> "befir"
I'm not 100% that it is related to removing the scorer from the API, but it is one thing I see changing between releases, and the documentation suggested accuracy improvements in particular.
Short: The scorer matches letter output from the audio to actual words. You shouldn't leave it out.
Long: If you leave out the scorer argument, you won't be able to detect real world sentences as it matches the output from the acoustic model to words and word combinations present in the textual language model that is part of the scorer. And bear in mind that each scorer has specific lm_alpha and lm_beta values that make the search even more accurate.
The 0.8.2 version should be able to take the scorer argument. Otherwise update to 0.9.0, which has it as well. Maybe your environment is changed in a way. I would start in a new dir and venv.
Assuming you are using Python, you could add this to your code:
ds.enableExternalScorer(args.scorer)
ds.setScorerAlphaBeta(args.lm_alpha, args.lm_beta)
And check the example script.

Libreoffice : italics breaking off (messes with replace-function)

I have been trying to use automatic replace function to place entries starting with italics on their own lines, so for example
lähteä60*F【动】
1. 离开, 出发, 走掉líkāi, chūfā, zǒu diào(poistua). Vieraat lähtevät.客人走了kèrén zǒule.Juna lähtee raiteelta kaksi. 火车两点离站huǒchē liǎng diǎn lí zhàn.
would turn into
1. 离开, 出发, 走掉líkāi, chūfā, zǒu diào(poistua).
Vieraat lähtevät.客人走了kèrén zǒule.
Juna lähtee raiteelta kaksi. 火车两点离站huǒchē liǎng diǎn lí zhàn.
However, for some reason unknown to me, the replace function (cf. screenshot) breaks up the lines like this:
lähteä60*F【动】
1. 离开, 出发, 走掉líkāi, chūfā, zǒu diào(poistua).
Vieraat lähtev
ä
t.客人走了kèrén zǒule.
Juna lähtee raiteelta kaksi. 火车两点离站huǒchē liǎng diǎn lí zhàn.
(so the first line "Vieraat lähtevät.客人走了kèrén zǒule." is broken up.)
As far as I can tell, it should be all italics, so I have no idea why it breaks up and no way to examine what's the problem. Trying to save to different formats doesn't seem to help either. There's thousands of pages of this stuff, so the automatic function is really required.
A small sample file of the stuff can be downloaded from here:

Requesting member of node_element results in "undefined"

I'm using Opa for a school project in which there has to be some synchronization of a textfield between several users. The easy way to solve this, is to transmit the complete field whenever there is a change performed by one of the users. The better way is of course to only transmit the changes.
My idea was to use the caret position in the textfield. As a user types, one can get the last typed character based on the caret position (simply the character before the caret). A DOM element has an easy-to-use field for this called selectionStart. I have this small Javascript for this:
document.getElementById('content').selectionStart
which correctly returns 5 if the caret stands at the fifth character in the field. In Opa, I cannot use selectionStart on either a DOM or a dom_element so I thought I'd write a small plugin. The result is this:
##extern-type dom_element
##register jsGetCaretPosition: dom_element -> int
##args(node)
{
return node.selectionStart;
}
This compiles with the opp-builder without any problem and when I put this small line of code in my Opa script:
#pos = %%caret.jsGetCaretPosition%%(Dom.of_selection(Dom.select_id("content")));
that also compiles without problems. However, when I run the script, it always returns "undefined" and I have no idea what I'm doing wrong. I've looked in the API and Dom.of_selection(Dom.select_id("content")) looked like the correct way to get the corresponding dom_element typed data to give to the plugin. The fact that the plugin returns "undefined" seems to suggest that the selected element does not know the member "selectionStart" eventhough my testcode in Javascript suggest otherwise. Anyone can help?
In Opa dom_element are the results of jQuery selection (i.e. an array of dom nodes). So if I well understood your program you should write something like node[0].selectionStart instead of node.selectionStart.
Moreover you should take care of empty selection and selection which doesn't contains textarea node (without selectionStart property). Perhaps the right code is tmp == undefined ? -1 : tmp = node[0].selectionStart == undefined ? -1 : tmp
